Equipped with the newly developed silent EX-FDB bearing, these fans are available in three sizes (80mm, 92mm and 120mm) with three different rpm models each.

The EX-FDB (Extra Fluid Dynamic Bearing) comes with a group of "V" shaped grooves, ensuring an even distribution of the oil film in the shaft housing and thus reducing friction to a minimum level. In this way, low noise and a lifespan of 120,000 hours (MTBF) can be achieved. Especially the low-speed versions are suitable for use in silent computer systems. For easy connection to PC power supplies, a 3-pin to 4-pin Molex adapter is included.
